Weathering is defined as the decomposition of minerals by chemical compounds attacking the crystal structure. Quartz is crystalline SiO2, a compound that is very resistant against all usual aggressive chemical agents (mostly acids in natural environments) and can be decomposed efficiently only by hydrofluoric acid (HF), which rarely occurs in nature.
All other common minerals can either be oxidized on the surface (metals and sulphides), dissolved (carbonates and evaporites), transformed into clay minerals (silicates).
Chemical weathering
Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chemical reactions, and gravity are some of the causes of weathering.
It causes chemical weathering because when it touches rocks, the rocks dissolve, forming caves.

what chemical weathering called oxidation causes
It causes any mineral to crack or leave little sediments of the remaining rock

Oxygen is the major gas that is the cause chemical weathering.
Physical, chemical and biological change are the three main causes of weathering.
